He works (or recently worked) for Mozilla on security-related projects. The code commit fixing the issue was isolated to the /dom/ directory in the source tree, and Firefox does not support CSS Animation Timelines. The Animation Timelines code is not directly accessed by web devs, and it appears the only way to execute that code is via the JS API for Animation Timelines. I'm not a web security expert, but the signs seem to point to him being correct.
Once again, JS proves to be a security risk.
I think it would be a labor of love and craftsmanship to exploit a content process today without using JavaScript.
